SCHMIDT AND' WILLIAM 13.THORN'ION,orrIIILAnEILr-IIIA;rENNsYLvAIIIAf This invention'is adaptedfor use lon f'a lfour-cylinderl high pressure locomotive engine. in'which two rcylinders are located at. the forward end of the locomotiveand two located some distance in the rear ofthe forward cylinders. n p y-larly adapted. to ak simple Malletffour?,` cylinderhighpressure engine.One object of theinvention yis to provideV 10` separate nozzles for theforwardand rear fcylind'ers,` and to have a common chamber fforthe'bleeding of exhaust steam from'l the.V nozzles, for thepurpose'ofsupplyin'gsteamV to an' exhauststeam feed waterheaterl In theaccompanying drawing: Fig. l is a side view, l.partlyV in section, illustrating our improvedexhaust nozzle struc-V ture; Fig. '2 is asectional planV viewon'the line 24-2,Fig.1; .l l. f

Fig. 3 is an end View; and f y Figli is a sectional view: on the lineReferring to the drawing, l' is theelrhaust nozzle of the forwardcylinders,` and 2 is the Y nozzlev forthe rear cylinders in the presentinstance. Connecting .the 'twoVV nozzles yis al easing 8, enclosing achamber whichjcommunicates with both nozzles-throughv-portsl 30 and 5,respectively,y inv the casings of the noz zles land 2. f

Thecasing 3 terminatesin apipe Shaving',-

a angef coupled 'to a pipe leadingxto a" feed water heater. The ycasingis so shapedfthat r exhaust steam can readily flow from the noz{ zlesintosaid chamber and' pass to the feed water heater. p
